This utility model discloses a bipolar plate for a flow battery with a conductive metal sheet, comprising a front electrode plate, an intermediate substrate, and a rear electrode plate. The front electrode plate is a conductive plastic sheet, the intermediate substrate is a metal sheet, and the rear electrode plate is also a conductive plastic sheet. The intermediate substrate is composite-extruded between the front and rear electrode plates. By forming the front, intermediate, and rear electrode plates into a composite bipolar plate, the conductivity of the bipolar plate can be increased through the intermediate substrate. Simultaneously, using a metal sheet for the intermediate substrate effectively ensures the strength and toughness of the bipolar plate, preventing brittleness and leakage. Since the front and rear electrode plates are made of plastic, the weight is reduced. This material combination provides a bipolar plate with better conductivity, lower porosity, and lower cost. Furthermore, the composite extrusion method simplifies the manufacturing process and makes it easy to implement.

The utility model provides a grease-proof corrugated board suitable for cold-chain logistics, which sequentially comprises a grease-proof coating, a low-temperature-resistant PLA (polylactic acid) lamination layer, a wavy buffer layer, a rebound filling layer, a degradable PE (polyethylene) preservative film layer, an oil-resistant coating, a honeycomb board layer, an oleophobic activated carbon non-woven fabric layer and a high-density corrugated paper inner layer from outside to inside, and the rebound filling layer is correspondingly arranged in a corrugated gap of the wavy buffer layer in a filling manner. High low temperature resistance and grease permeation resistance are realized.
